Yes, http://www.gap-system.org/Manuals/doc/htm/ref/CHAP037.htm#SECT007 sage: S = SymmetricGroup(4) sage: G = gap(S) sage: g = G.Random() sage: h = G.Random() sage: g; h (2,3,4) (2,3) sage: H = G.Subgroup([g,h]) sage: k = G.Random() sage: k (1,2,3) sage: H.RightCoset(k) RightCoset(Group( [ (2,3,4), (2,3) ] ),(1,2,3)) Basically, GAP creates a new data structure for right and left cosets. Sage could implement this by creating a new coset class, with "right" or "left" options.. > > William > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sage-edu" group.
